Title: Magnetic video recording device
Inventor: KANAZAWA YOSHIKAZU
IPC: H04N5/782
Filed: 1983-05-09
Abstract: PURPOSE:To compensate a position shift of a horizontal synchronizing signal between adjacent tracks by making the moving amount of running period of each tape coincident with one frame's share of continuous feeding and give a displacement to a magnetic head in an intermittent recording of a VTR. CONSTITUTION:The position of the 2nd magnetic head M2' is displaced to the position of the 1st magnetic head M1 by advancing it from a symmetrical position relating to the center of rotation to the circumferential direction by H(Sa). In feeding a tape of a VTR on market in the standard speed, though disturbance is remarkable because the tape speed recording traces a1, b1 for one frame's share is decreased from the standard speed owing to the transient rise of a capstan motor and the content of signals differs while the arrangement of horizontal synchronizing signals for adjacent tracks is not conducted, since the magnetic head M2 is displaced by an interval Sa advanced by the tape in 1/ 60sec being 1 field in the ordinary continuous recording by recording signals by means of the magnetic drum provided with this head, the shift is compensated and the disturbance is prevented.

Title: Photoelectric converter formed on base board
Inventor: INOUE NAOHISA
IPC: G02F3/00
Filed: 1985-04-19
Abstract: PURPOSE:To perform highly efficient photoelectric conversion by radiating the rays of light propagated through an optical wave guide in the direction of a high-refractive index layer mounted on the optical wave guide when the rays of light reach the part of the layer and causing the rays of light to be made incident on a photovoltaic element. CONSTITUTION:An input optical signal Iin is introduced to the 1st optical wave guide 11 and a reference light IinR is always inputted in the 2nd optical wave guide 12. An output optical signal Iout is obtained from the 3rd optical wave guide 13. Since no electromotive force is generated from a photovoltaic element 15 when the input optical signal Iin is '0', no voltage is applied across electrodes 14. Therefore, 100% of the rays of light propagated through the optical wave guide 12 are shifted from a directional coupler to the optical wave guide 13 and the output optical signal Iout becomes '1'. When the input optical signal Iin is '1', a voltage is generated across the photovoltaic element 15 by the rays of light propagated through the optical wave guide 11 and the voltage is applied across the electrodes 14. Therefore, the rays of light propagated through the optical wave guide 12 are not shifted from the directional coupler to the optical wave guide 13, but propagated through the optical wave guide 12. Accordingly, the output optical signal Iout becomes '0'.

Abstract: PURPOSE: To obtain a television camera with color separation prisms for solid-state pickup elements with the length shortened in the nonreflection-light-axis direction, by tilting in the same direction two dichroic films arranged between color separation prisms.  
     CONSTITUTION: Among prisms 6, 7 and 8 constituting color separation prism 2, dichroic film 9 arranged between the junction surface of prism 6 and the incident surface of prism 7 reflects the blue or green component of light from object lens 1 to form a unicolor image of blue or green on solid-state pickup element 5. Dichroic film 10 arranged between the junction surface of prism 7 and the incident surface of prism 8 reflects the red or blue component to form a unicolor image of red or blue on solid-state pickup element 4. Then, light having passed through film 10 forms a unicolor image of green or blue on solidstate pickup element 3. Here, films 9 and 10 are tilted in the same direction for miniaturization.

Title: Logic circuit
Inventor: MATSUMOTO HIROSHIGE
IPC: H03K19/086
Filed: 1987-04-02
Abstract: PURPOSE:To eliminate the shift in the output potential caused by a ground wire resistor by using a constant current circuit between an output terminal of a CML logic circuit and a power supply. CONSTITUTION:Constant current circuits 12, 13 are used to give a current to resistors 9, 10 in a direction from a power terminal 6 toward ground to raise the potential at output terminals 3, 4 by 1/2rIV to nearly cancel the potential shift of -1/2rIV thereby obtaining nearly the ideal potential level of the output terminal 3, 4, that is, high level 0V and low level -IRV. Assuming a current flowing through the constant current circuits 12, 13 as iA, since the current iA flows to the resistors 9, 10 to raise the potential of the output terminals 3, 4 by -rIV, the relation of i=1/2r/RIA is obtained. Thus, the current (i) is enough for the purpose.

IPC: F23G5/02
Filed: 1995-04-07
Abstract: PURPOSE: To provided a feeding device and method by which waste tires can be constantly fed into a combustion furnace, and a stable combustion can be ensured. CONSTITUTION: Waste tires 1 are fed to a reactor by a charging hopper 2. The fed waste tires 1 are first crushed and mixed by a crushing blade 4 to be evened. Then, the reactor is tapered in toward the tip, the waste tires 1 are compressed, and of which the volumes are reduced while being continuously transferred to the tip.

Title: Phtoelectric conversion device
Inventor: SAITO KAZUO
IPC: H04N5/335
Filed: 1985-04-19
Abstract: PURPOSE:To prevent cross talk and to improve resolution, by taking out carriers, which undergo photoelectric conversion at a deep part of a substrate directly beneath a picture element, as a picture element signal to the surface, and discharging the carriers, which are diffused in the direction of neighboring picture elements, to the substrate at the shallow part of a well region. CONSTITUTION:On the surface of a semiconductor substrate 1, an insulating film 4 such as a silicon oxide film is formed. A reverse bias voltage is applied between each of p-type well regions 3a, 3a... and an n-type semiconductor substrate 1. Carriers, which are generated in each well region 3a and moved to neighboring picture elements, pass the reversely biased semiconductor substrate 1. The carriers are discharged to the semiconductor substrate 1. Even if each p-type well region 3a is formed relatively deeply in order to discharge the carriers to the substrate at the boundary part of each p-type well region 3a, cross talk can be prevented. By forming each p-type well region 3a deeply, a red color - an infrared color having long wheel wavelengths, which penetrate into the deep part in the substrate, can sufficiently undergo photoelectric conversion. Thus the crosstalk can be prevented prevented and resolution can be improved without decreasing to the incident light on the long wavelength side.

Title: Driver of recorded disk reproducer
Inventor: FUKUMITSU AKIRA
IPC: G11B17/04
Filed: 1983-05-13
Abstract: PURPOSE:To simplify both the mechanical constitution and the constitution of an electric circuit for the titled driver by using a driving source and a tension spring which energizes an up/down slider or a twist lever connecting a carriage and the up/down slider to feed an arm and at the same time moving up and down a turntable. CONSTITUTION:When a reset mode is changed to a reproduction mode, the revolution of a drive motor 45 is transmitted to a final gear 48a. Then the gear 48a revolves clockwise as shown by an arrow E, and a carriage 41 moves toward the arrow E. Then a twist lever 54 shifts a slider 49 toward an arrow A by the force of a spring 58. A turntable 53 moves up to keep a disk 60 at a fixed height. The shift of the slider 49 is stopped by a stopper 49e, and the lever 54 is stopped. Thus a pin 55 of the lever 54 is detached from a pin holder 41b of the carriage 41. Therefore the carriage 41 and an arm 42 are driven independently of each other. When the arm 42 reaches the landing position L, a signal reproduction stylus 42a moves down to start reproduction.

Abstract: PURPOSE:To obtain a clear picture free from secondary phase error by finding a required parameter by a parameter arithmetic unit, and calculating the required quantity of secondary phase compensation from this value by a secondary oscillation compensator. CONSTITUTION:A compensation value of secondary phase error is found by using an external input 17 given to a parameter arithmetic unit 16 and the speed of an aircraft obtained from an inertial navigation system 14.
